Benthic foraminifera fauna and microfacies characteristics of the jurassic-lower cretaceous Cehennemdere formation at Taşucu-Aydıncık (Mersin) areas

Benthic foraminifera fauna and microfacies characteristics of the Jurassic-Lower Cretaceous Cehennemdere Formation were investigated by two measured stratigraphic sections from Taşucu-Aydıncık (Mersin) areas where its typical outcrops occur. 98 samples were collected from the 250 m thick Taşucu (Silifke) section, and 33 samples, from the 270 m thick Aydıncık section. A benthic foraminifera fauna consisting of Bosniella croatica, Everticyclammina sp., Kilianina sp., Kurnubia jurassica, Nautiloculina circularis, Nautiloculina oolithica, Paleopfenderina salernitana, Paleopfenderina trochidea, Pseudomarsonella maxima, Preakurnubia sp., Redmondoides lugeoni, Satorina apulensis, Siphovalvulina variabilis was defined from the Aydıncık section, and a benthic foraminifera fauna consisting of Arenobulimina sp., Belorussiella sp., Haplophragmoides sp., Kurnubia ex. gr. palestiniensis, Kurnubia jurassica, Siphovalvulina variabilis, Mayncina bulgarica, Praechrysalidina infracretace from the Tokmar section. The Aydıncık section was deposited in an environment extending from supratidal to shallow-subtidal and lagoon, and the Tokmar section in a lagoon enviroment..
